To @ZZ whom, t 71mg/ con/corre:

Be it known that I, WILLIAM F. HUrcHIN- SUN, of Bound Brook, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Vire-Nail Machines, of which the following is a full, clear, and exact description.

My invention relates to improvements in nail-machines, and particularly to machines adapted to form nails from a continuous wire.

The object of my invention is to produce a comparatively simple machine in which rotary dieing-rolls are used and also a rotating table to receive the partially-formed nails and complete the formation of them, this rotary principle being adapted to make nails with great rapidity and also form perfect nails.

A further object of my invention is to produce a machine which is entirely automatic and not likely to get out of repair, to the end that the production of nails may be cheapened.

'W ith these objects iupview my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specication,

in which similar gures of reference indicate corresponding parts in all the views.

Figure 1 is a broken vertical cross-section on the line 1 1 of Fig. e of my improved machine, showing the wire as it is fed into the machine and cut into nails. Fig. 2 is a broken detail plan view, partly in section, of the carrying-table which revolves beneath the dieing-rolls and receives and finishes the partially-formed nails. Fig. 3 is a detail edge view, partly in section, of the said carryingtable. Fig. ais a central longitudinal section on the line 4 tot Fig. 1; and Fig. 5 is a detail view, partly in section, of the dies used in completing the nail-point after it has been partially formed by the dieing-rolls.

The machine has a suitable frame 10, which carries the parallel and oppositely-arranged dieing-rolls 1.1, each of which is grooved, as shown at 12, to receive the wire or stock 13, and iu the grooves of the rolls are transverse dies 14, the distance between which corresponds to the length of a nail to be cut, allowmany ways, but, as illustrated, they are carried by shafts 15, which 'are journaled in suitable bearings and one of which connects by gears 16 and 17 with the main driving-shaft 1S, this being also journaled on the frame and provided with a ily-wheel 19 or other suitable driver, and the second shaft 15 is geared toa gear-wheel 20 on the opposite shaft, as sho wn clearly in Fig. 4. The details of the driving mechanism are not carried out, because it is obvious how the driving is accomplished and that the shafts can be rotated in many ways. The dies let do not quite sever the wire 13, and after being incised it passes downward through the guide 21, opposite a verticallyarranged die 22, which is held on the abutment or facing 23 of the bracket 21 by a faceplate 25, (see Figs. 4 and 5,) which is screwed to the bracket. The die 22 has an inverted-V- shaped slot 22 at the bottom, (see Fig. 5,) in which lits the opposite or male die 26, formed on'the bar 27, these dies 26 and 27 being arranged in series on the table 2S, which rotates on a vertical axis, so that the dies 26 successively engage the slot 22a of the die 22. By reference to Figs. 1 and 5 it will be observed that the planes of the sides of the slot 22iL are at right angles to the planes of the incisions made by the dies 1e, so that as the nails 13 (see Fig. 1) are pushed by the dies 26 through the die 22 the points of the nails will be completed and said points will be four-sided.

When the partially-formed nails on the wire 13 are fed downward by the rolls 11, they enter the annular groove or guide-slot 23 (see Y IOO dened pieces therefore act as ixed and the clamping-jaws '81 as movable jaws. As the `wire 13k is fed downward the partially-formed Vnail 13@L extendsdownward through the slot 28, and when the first hole 29 is reached the nail is clamped by the clamping-jaw 3l, which has a slightly-inclined or cam-shaped outer edge and which at th is point isV forced firmly inward kagainst the nailY by an abutment-roll 85,

. l which is journaled on a vertical anis directly Voppositethe plane ofthe wire or'n'ail, as

The nail is'headed on the under sid-e, and

Y to prevent or rather resist the upward thrust Vduring theheadin g operationl rolls are used,

` Y YWhen the nail 13a drops into which bearon the upper side of the table 28,

opposite the part where the `heading takes plaee,these rolls being journaled on the bracket 24, already referred to, whichy bracket slides vertically on the frame 10 and can Vbey adjusted by the ordinary Vadj usting-wedges 37, V(see Fig.1,) whiclrwedges Lhave' lugs'SS, through which extend adjusting-screws-39,

which enter the bracket 24 on opposite sides.

The wedgesioverlap, and byy moving them in and out the height of the bracket is regulated.

eden ball-bearings 41 (see Fig-.4) and at the top connects by the bevel geauwheels 42 and 43- with the main shaft 18. l

the'table 28, is clamped, and has its point completed, as above specified, its lower end projects through the table and rests on one of a series of plungers 44, which plungers are carried in a rotating carrier 45, each plunger being vertically movable and being prevented from falling out of the carrier by means of a pin 44a o'n the plunger, which enters a slot 44b in the carrier.' Any other suitable contrivance may be used for preventing the displacement of the plungers. The carrier 45 is rotated so that a plunger 44 will be moved upward and strike and form the head of the nail While the nail is clamped, as above described, and, as illustrated, the carrier is secured to a vertical shaft 46, which connects by a gear-Wheel 47 with a gear-wheel 4S on the shaft- 40, and the said gear-wheel 48 also connects by idlers 49 and 50 with a gear-wheel 51 on the shaft the nail is held and just as its point is being completedthe plunger is forced upward by the said roll and striking against the lower end of the nail the head on the latter is formed by the blow. The roll 55 is carried on a shaft 56, which is journaled on a bracket-57, the latter being adjusted vertically by the ordinary adjusting and overlapping wedges 5S, Y Y

which are moved by the screws 5i), extending Vthrou gh lugs on the end of the wedges and en-Y tering the aforesaid bracket.

The operationV of the machine isas follows:

The wire 13,*from which thenails are'fcrmed, isffeddownward between the dieing-rolls 11, the said rolls being self-feeding, although au independent feed maybeused, if desired. Y

. s ewire rocee s Aie rei terinffte A th p d tl cb sL g l1s14 make inclined impressions inthe wire, the.

opposite sides` thusV forming two sides of aV nail-point, and as the wireV is fed downward f through the guide 21 passes opposite the die nail is securely held theplunger 44 strikes I the lowerV end o-fit,y the said plunger being forced up by the roll 55, and at practically Vthe Vsame instant the advance of the table 2S causes one yof the dies V261:0 push the nailV Y through the slot 22Bv of the die ,22, thusV completingthe nailepoint. As the nail is carried l beyond the carrier 45 it drops'from the table 28.' It will be noticed'that ythe dies 26and Vclamping devices advance in quick succession, andas the feed is ltimed so as to bring a nail in place as fastl as the clamps are worked it will be seen that the nails are very rapidly formed, for the machine can be run at a comparatively high speed. The guide-slot 2S in the table is important in this connection, as it enables the feed to be speeded high, and without some such contrivance it would be difficult to guide the nail into a clamping dev1ce.

I do not wish to limit my invention to the particular arrangement of parts illustrated, as I believe that my system of forming half the nail-points with the rotating dieingrolls, then clamping the nail-blank, forming the remainder of the point, and making the head is broadly new, and that the details of construction can be changed considerably without affecting the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-v i 1. A nail-machine comprising oppositelyarranged dieing-rolls constructed to form a portion of a nail-point, finishing-dies to form the remainder of the nailepoint, a series of clamping devices to successively engage the nail-blanks and carry them through said finishing-dies, and a heading device acting while the nails are in the clamps, substantially as described. v

2. A nailmachine comprising oppositelyarranged di'eingerolls constructed to form a IOC IIO

portion of a nail-blank between them, a stationary die lying essentially parallel with the blanks as they are discharged from the dieing-rolls, a series of clamps to receive the blanks, a series of traveling finishing-dies movable with the clamps and adapted to pass through the stationary die to nish the nailpoints, and reciprocating heading devices movable opposite the clamps, substantially as described.

3. The combination of the stationary die, the traveling clamps opposite the die, the movable dies arranged in series with the clamps and adapted to force the nail-blanks through the stationary die, and a heading device adapted to successively strike the nailblanks as they are caught by the clamps, substantially as described.

`4. The combination with the stationary die, of the rotating table movable opposite the end of the die, the nail-clamps carried by the table, the dies carried by the table and arranged in series with the clamps, said tablehaving a continuous guide-slot therein, of

the jaws arranged at intervals on opposite sides of said guide-slot and adapted to close upon blanks held in the slot, substantially as described.
